Impact response of sandwich composites reinforced with metal wastes under single and repeated low-velocity impact loads

Abstract

In this study, the impact response of sandwich composites with four different metal reinforcement weight ratios (0%, 3%, 5%, and 10%) under single and repeated low-velocity impact loads was investigated. The permanent deflection did not occur at the energy level of 10 J, but it occurred at higher energy levels. Increasing the temperature has a significant effect on the repeated impact strength of the sandwich composites with metal reinforcement, similar to the sandwich composites without metal waste reinforcement. The low-velocity impact test results indicated that the number of impacts causing full perforation decreased as the impact energy levels increased.
